Golf club head construction
First Claim
1. A golf club head comprising a face plate having a strike face, a structural support comprising a shell structure circumscribing an interior space, and having a first end and a second end, the first end of the shell structure being joined to a side of the face plate opposite from the strike face near the perimeter of the strike face, the shell structure having a cross sectional shape approximating the shape of the perimeter of the strike face, the second end of said shell structure terminating at a location spaced from the face plate in a direction extending away from the strike face, and an element for attaching a shaft joined to the shell structure.

Abstract
A golf club "wood" of hollow construction includes a shell or wall which is attached to the back side of the face plates and extends rearwardly to a mass mounted as part of the head. The shell or wall is relatively straight in the load bearing direction and is preferably corrugated to suppress buckling failure. The shell or wall may be cast, or if desired thinner sections may be made of sheet material and assembled to support the face by means of welding, silver brazing, or for certain materials, gluing in place. An outer cover may be added to preserve an approximately traditional external shape or to permit other freedom of design of the external shape. The cover is lightweight construction such as fiber-reinforced plastic, or a very rigid foam plastic material.

- 15. A golf club head shell comprising a face plate having a strike face, a shell structure of thin material formed around an axis extending in direction away from the strike face on a opposite side of the face plate from the strike face and circumscribing an interior space surrounded by the shell structure, a first end of the shell structure being joined to a side of the face plate opposite from the strike face near the perimeter of the strike face, the first end of the shell structure having a cross sectional shape approximating the shape of the perimeter of the strike face, a second end of said shell structure having a smaller cross section than the first end and terminating at a location spaced from the face plate in direction extending away from the strike face, and a mass block attached rigidly to the second end.
